RYANAIR pilots have been offered a one-off bonus of up to £12,000 to give up holidays in a last-ditch effort by the airline to prevent further flight cancellations.
Around 400,000 passengers have now been contacted by Ryanair to say the flights they booked no longer exist.
Belfast routes are not affected, but Dublin has experienced a slew of cancellations.
Up to 50 flights a day will be cancelled until October 31.
Irish Air Line Pilots' Association (IALPA) has accused the carrier of making European regulations a scapegoat, claiming Ryanair bosses failed to allocate enough pilots for its schedule.
Ryanair could face further disruption from industrial action as it is reported pilots are meeting across Europe to discuss going on strike.
The airline's chief executive Michael O'Leary has admitted to a "cock up" over pilot shortages that led him to cancel flights and disrupt the plans of hundreds of thousands of passengers.
He has estimated that Ryanair will face a €20 million compensation bill and it looks set to be further out of pocket by the time the crisis is resolved.
Internal emails show that the budget airline is attempting to appease pilots and first officers by offering tax-free bonuses not to take time off, according to the Guardian.
It quotes Ryanair's chief operations officer, Michael Hickey writing to pilots: "To avoid further cancellations, we are requesting between one and two blocks of five days from every pilot who has already been assigned their month off.
"In recognition of the impact on you of the need to fly additional days I am implementing the following bonus scheme. All current pilots [...] who remain operating Ryanair aircraft between Sept and October 31 2018 will receive a once-off €12,000/£12,000 gross bonus for captains and €6,000/£6,000 for first officers in November 2018."
With pilots not receiving the one-off bonus until next November, it is being interpreted as an inducement to stay with the company after reports that many are defecting to Norwegian Air.
The rival says it has hired 140 pilots from the Irish airline since January.
